The INSTANCEOF operator in reference qualifiers

You can use the INSTANCEOF operator in a reference qualifier to shorten or simplify a
complex class qualifier.

that all subclasses of a class are included in the results. The following reference qualifier
returns all servers, including Linux, UNIX, Windows, and so on, because each of those
subclasses extend the cmdb_ci_server class.

sys_class_nameINSTANCEOFcmdb_ci_server

In another example, you can simplify the following reference qualifier in a similar way.
